Nonmetal or non-metal is a chemical element that does not have the properties of a metal. A non metal is also a good insulator for heat and cold. Usually, gases or brittle solids are non-metals. Elements on the periodic table can be classified as metal, semimetal, or non-metal. Example are hydrogen, helium, carbon, nitrogen, oxygen, fluorine, neon, phosphorus, sulfur, chlorine, argon, selenium, bromine, krypton, iodine, xenon, and radon.
